"I enjoyed my stay at Celtic and I am always grateful for the contribution the club made into my development," he tells Chiefs official website.
"However, there will be no room for sentiment when we come face to face at Nelson Mandela Bay Stadium. We are hosting the game at a historic World Cup venue and we want to leave a lasting impression!"
Moleko, who last played in Amakhosi's 6-0 drubbing of AmaZulu in the season opener, was in the starting line-up for the match against Chippa United, after Siboniso Gaxa picked up an injury against Bidvest Wits.
The 23-year-old says he was prepared to step into the fold, after hard work at training.
"I worked hard at training and of course you have to be ready to play just in case the technical team calls you up to do duty for the team," he says.
"I was pleased with my contribution and did not struggle to adapt to the pace of the game. There is always room for improvement and I will continue to work hard and listen to the technical team."
Moleko says Chiefs still have "a long way to go" this season, and are already looking ahead to the weekend.
"It is important that we keep our feet on the ground. We are pleased with the win but we all have to agree that we have a long way to go. We have another tough encounter this coming weekend," he says.
